Answer:

  • volume: 18 ft³
  • surface area: 42 ft²

Explanation:

The volume of a cuboid is the product of its dimensions:

V = LWH = (3 ft)(3 ft)(2 ft)

V = 18 ft³

The area is the sum of the areas of the faces. Since opposite faces have the same area, we can figure the area from ...

A = 2(LW +H(L+W)) = 2((3 ft)(3 ft) +(2 ft)(3 ft +3 ft)) = 2(9 ft² +12 ft²)

A = 42 ft²
